How to calculate average
Hi,
I have 2 sheets,
Sheet 1 – Result of evaluation – there is only 1 record per 1 person, and everyone has the evaluation result on the same date – 31/01/24
Example of raw data
Units | Result of evaluation | Date |
Marketing | 1 | 31/01/24 |
Marketing | 3 | 31/01/24 |
Finance | 2 | 31/01/24 |
Finance | 2 | 31/01/24 |
Finance | 3 | 31/01/24 |
Operations | 3 | 31/01/24 |
Operations | 3 | 31/01/24 |
Operations | 4 | 31/01/24 |
Sheet 2- List of resign employees – which shows the ‘Result of evaluation’ that was merged from the sheet 1.
Example of raw data
Units | Employee ID | Result of evaluation | Terminate Date |
Marketing | 1111 | 1 | 31/01/24 |
Finance | 3333 | 2 | 15/03/24 |
There is no relationship between these 2 sheets because once I create the relationship it said that it will cause ambiguity.
And the one result that I’ve been longing for is to calculate the average of Result of evaluation so that I can calculate the attrition rate after this.
This is what I have on Excel
| Sum of Result of evaluation 1-3 (4 was not counted) | January - number of terminations in Jan | No termination in February | March - number of terminations in March |
|
Units | January | February | March | April | Average |
Marketing | 2 | 1 | 1 | 1 | 1.25 |
Finance | 3 | 3 | 3 | 2 | 2.75 |
Operations | 2 | 2 | 2 | 2 | 2 |
So after I got the average I can calculate the attrition rate like this (number of terminations / average)
Units | January | February | March | April |
Marketing | 50% (1/2) | 67% (1/1.5) | 75% (1/1.33) | 80% (1/1.25) |
Finance | 0% | 0% | 33% (1/3) | 36% (1/2.75) |
Operations | 0% | 0% | 0% | 0% |
But now the current measure I got brings me the wrong answers, it's only correct when at the end of the year (e.g. only the attrition rate in December is correct)
So please help suggest how to calculate the attrition like above table.
Thank you in advance. 🙏🙏

Anonymous I'm not quite following this. I get the 2 for Marketing for January. I don't get the rest of the columns. You have a February month but this lists the number of terminations that happened in January? Where are the other 2 columns coming from (no terminations in February for March and number of terminations in march for "April". Thoroughly confused.
Sorry, having trouble following, can you post sample data as text and expected output?

The most important parts are:
1. Sample data as text, use the table tool in the editing bar
2. Expected output from sample data
3. Explanation in words of how to get from 1. to 2.Sorry for my confused explanation.
Let me explain again
1. Sample data as text, use the table tool in the editing bar
Sample data table 1 - Total Headcount
Employee ID Business Unit Result 00001 Marketing 1 00002 Marketing 1 00003 Marketing 2 00004 Marketing 3 00005 Marketing 2 00006 Marketing 4 00007 Marketing 1 00008 Marketing 1 00009 Operations 2 00010 Operations 4 00011 Operations 2 00012 Operations 4 00013 Operations 2 00014 Operations 1 00015 Finance 1 00016 Finance 1 00017 Finance 3 00018 Finance 3 00019 Finance 3 00020 Finance 3 Sample data table 2 - Termination
Employee ID Business Unit Result Effective Date 00004 Marketing 3 05/01/2024 00006 Marketing 4 15/01/2024 00011 Operations 2 22/02/2024 00017 Finance 3 02/03/2024 00003 Marketing 2 05/04/2024 There are no relationship between table 1 and table 2
but table 1 and table 2 have relation with the Business Unit that was set as a primary key (all unique)
and table 2 has relation with date table
2. table 3 - Expected result
Business Unit Attrition Finance 17.4% (1/5.75)
Marketing 32.0% (2/6.25) Operations 28.6% (1/3.5) Total 25.8% (4/15.5) 3. Explanation in words of how to get the result from 1. to 2.
- The attrition from table 3 is calculated from Total of termination (table 2) / Average headcount (that will be calculated from table 1)
- Average headcount is calculated from table 1
for example:
Beginning Balance
JanFeb Mar Apr Average HC Finance 6 6 6 5 5.75 Marketing 7 6 6 6 6.25 Operations 4 4 3 3 3.5 Total 17 16 15 14 15.5 (I can't find the solutions to calculate this table, this table is calculated on Excel)
Beginning Balance is summarized from table 1 with filter only the result 1-3 (excluded 4)
and then there was 1 person who got the result 3 in marketing resigned in January so the total headcount in Feb decreased from 7 to 6.
and then, another person in Operations left in February, so total headcount in March was 3.
So if I can find the average headcount then I can find the attrition that is calculated from termination / average headcount
Please let me know if you need more information
Thank you
